P\TΔ2-3 lacks a tissue-specific intron that normally limits transposase activity to the germline.
The last intron, which is responsible for the limitation of transposase activity to the germline, has been deleted. P\TΔ2-3 therefore produces transposase in both the somatic and germ cells.
Precise deletion of the intron sequences at the ORF2 and ORF3 junction.
report comment: Note: Identity of promoter as Hsp70 may be suspect; see report for pUChsΔ2-3. Heat shock not necessary for high levels of expression.
construct_comment: Constructed in W. Gelbart lab.
construct_comment: Source virtually immobile upon exposure to P-element transposase (appears to be an extremely low level of cross-mobilization, thus not completely stable).Able to transposase upon exposure to H-element transposase."HOP" for "hobo on P" or "hobo outside P".
